Fuji Electric GYS500D5-HB2-B Servo Motor: Powering High-Torque Applications with Unwavering Precision and Safety

In the upper echelons of industrial automation, where high torque, robust construction, and functional safety converge, the selection of a drive component becomes a critical determinant of overall system performance. The Fuji Electric GYS500D5-HB2-B is a high-capacity AC servo motor engineered specifically for these demanding scenarios. This model transcends the capabilities of standard servos, delivering substantial power in a compact frame, all while incorporating an integrated safety brake for controlled operation in vertically-oriented and high-inertia applications. This exhaustive guide provides a detailed examination of the GYS500D5-HB2-B's specifications, its technological advantages, and its pivotal role in heavy-duty automation, offering invaluable insights for system architects and design engineers.

The "GYS500" designation immediately signals a motor from a higher power class compared to the 100W models, typically indicating a 500W platform. The "-HB2-B" suffix is a multi-faceted descriptor: the "H" often points to a specific high-resolution encoder, the "B2" to a particular mechanical configuration or connector type, and the final "-B" confirms the inclusion of a critical electromagnetic holding brake. This combination makes the GYS500D5-HB2-B an all-in-one solution for applications that require significant force, precise positioning, and guaranteed safety in the event of a power loss.

The table below provides a meticulous breakdown of the motor's performance characteristics, with a dedicated section for the brake's specifications.

Strategic Advantages and Performance Features

1. High Torque Density for Demanding Applications
The GYS500D5-HB2-B is engineered for high torque density, meaning it delivers a significant amount of torque (1.59 N·m continuous, 4.77 N·m peak) from a relatively compact frame. This high torque output is essential for applications that require substantial force, such as pressing, stamping, or lifting heavy components. The 3:1 peak-to-rated torque ratio provides a generous reserve for dynamic acceleration and overcoming unexpected load increases, ensuring consistent cycle times and process reliability.

2. Integrated Safety Brake for High-Inertia and Vertical Loads
The fail-safe electromagnetic brake is a cornerstone of this motor's design, especially critical given its power rating. In vertical axis applications (Z-axes), robotic arms, or any system where the load can cause back-driving, the brake acts as a mechanical lock upon power loss. This prevents catastrophic drops, protects valuable equipment, and ensures personnel safety. The brake's holding torque of 5.0 N.m is specifically calculated to securely hold the loads that a 500W motor is designed to move.

3. Exceptional Positional Accuracy with High-Resolution Feedback
The integration of a 24-bit absolute encoder provides over 16 million counts per revolution. This extreme resolution allows for incredibly precise position control, making the motor ideal for applications like precision machining, semiconductor fabrication, and high-accuracy dispensing. The absolute nature of the encoder means the motor knows its exact position immediately upon power-up, eliminating the need for a homing routine and boosting machine productivity.

4. Ruggedized Construction for Challenging Environments
An IP67 protection rating makes this motor exceptionally robust. It is completely protected against dust ingress and can withstand temporary immersion in water. This makes it suitable for the most demanding industrial settings, including food and beverage processing (resistant to washdowns), metalworking (protected from coolants and metal chips), and outdoor applications where exposure to the elements is a concern.

Target Applications and Industrial Deployments

The power and features of the GYS500D5-HB2-B make it a prime choice for a range of heavy-duty automation tasks:

• Heavy-Duty Robotics: Acting as the primary actuator in the joints of larger industrial robots for welding, material handling, and assembly.

• Machine Tool Automation: Powering automatic tool changers (ATCs) in large machining centers, pallet changers, and tailstocks that require high clamping force.

• Packaging Machinery: Driving the main forming and sealing arms on high-speed packaging machines for heavy products.

• Material Handling: Operating as the drive unit for heavy-duty conveyor lifts, automated storage and retrieval systems (AS/RS), and elevator mechanisms.

• Test and Simulation Equipment: Providing precise and powerful actuation in dynamometers, fatigue testers, and flight simulators.

Integration and Operational Guidelines

To harness the full potential of the GYS500D5-HB2-B, adherence to specific integration protocols is essential:

• Proper Drive Sizing: This motor must be paired with a servo amplifier capable of delivering the required continuous and peak current (e.g., 3.0 A / 9.0 A). A Fuji Electric drive from the ALPHA7 series is recommended for optimal performance and access to advanced tuning features.

• Inertia Mismatch Considerations: While the motor has a higher inherent rotor inertia, it is still crucial to calculate the load-to-motor inertia ratio. For highly dynamic applications, keeping this ratio below 10:1 is advisable for stable control and responsive performance.

• Brake Control and Safety Integration: The brake should be controlled via a safety relay or the dedicated Safe Torque Off (STO) function of the servo drive. The control system must implement a timing delay to ensure the brake is fully released before the servo is enabled to produce torque.

• Thermal Management: Even with Class F insulation, ensure adequate airflow around the motor body. For extreme duty cycles, consider using an external blower or a forced-ventilated motor variant to maintain optimal operating temperatures and maximize service life.

Conclusion: The Definitive Solution for High-Power, Safety-Critical Motion

The Fuji Electric GYS500D5-HB2-B stands as a benchmark for high-performance servo technology in the mid-power range. It successfully integrates substantial torque output, exceptional positional accuracy, and a critical safety braking function into a single, ruggedized package. By selecting this motor, engineers and machine builders empower their designs to handle heavier loads, operate with greater precision, and achieve the highest levels of operational safety. For automation challenges where power, precision, and safety cannot be compromised, the GYS500D5-HB2-B is not just a component—it is a strategic asset.
